Cold Weather Operation

Cold Weather Operation
Perkins Diesel Engines can operate effectively in
cold weather. During cold weather, the starting and
the operation of the diesel engine is dependent on
the following items:
•
The type of fuel that is used
•
The viscosity of the engine oil
•
Optional Cold starting aid
•
Battery condition
The operation and maintenance of an engine in
freezing temperatures is complex , because of the
following conditions:
•
Weather conditions
•
Engine applications
Recommendations from your Perkins distributor are
based on past proven practices. The information that
is contained in this section provides guidelines for
cold-weather operation.
Hints for Cold Weather Operation
•
If the engine will start, operate the engine until a
minimum operating temperature of 81 °C (177.8 °F)
is achieved. Achieving operating temperature will
help prevent the intake valves and exhaust valves
from sticking.
•
The cooling system and the lubrication system
for the engine do not lose heat immediately upon
shutdown. This means that an engine can be shut
down for a time and the engine can still have the
ability to start readily.
•
Install the correct specification of engine lubricant
before the beginning of cold weather.
•
Check all rubber parts (hoses, drive belts,) weekly.
•
Check all electrical wiring and connections for any
fraying or damaged insulation.
•
Keep all batteries fully charged and warm.
•
Check the air cleaners and the air intake daily.
Personal injury or property damage can result
i04564559
from alcohol or starting fluids.
Alcohol or starting fluids are highly flammable and
toxic and if improperly stored could result in injury
or property damage.
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
Viscosity of the Engine Lubrication
Oil
Correct engine oil viscosity is essential. Oil viscosity
affects the amount of torque that is needed
to crank the engine. Refer to Operation and
Maintenance Manual, "Fluid Recommendations" for
the recommended viscosity of oil.

Recommendations for the Coolant

Provide cooling system protection for the lowest
expected outside temperature. Refer to this Operation
and Maintenance Manual, "Fluid Recommendations"
for the recommended coolant mixture.
In cold weather, check the coolant often for the
correct glycol concentration in order to ensure
adequate freeze protection.
Coolant Jacket Heaters
If installed, the coolant jacket heater heats the engine
jacket coolant that surrounds the cylinder block. This
added heat provides the following function:
•
Startability is improved.
An electric heater can be activated once the engine
is stopped. An effective heater is typically a 1250
W at 120 V. If your engine is to operate in a cold
environment, consult your Perkins distributor for more
information. An oil pan heater may also be required.
